Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a lug wrench and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check both sides for wear; replace if any pad is below 3mm thickness.
Replace Brake Pads (if necessary):
1. Remove the caliper bolts using a socket set.
2. Gently lift the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake hose).
3. Remove the old brake pads and install new pads, ensuring they are properly seated in the caliper bracket.

4. Check and Clean Brake Rotors

Inspect the rotors for any signs of warping or scoring. If damaged, replace rotors.
Clean the rotor surface with brake cleaner to remove debris and ensure proper pad contact.

5. Reassemble Components

Reinstall the caliper and tighten the bolts to the manufacturer's specifications (usually around 25-35 Nm).
Put the wheel back on and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Lower the vehicle off the jack stands.
Tighten the lug nuts to manufacturer specifications (usually a torque of 90-120 Nm).
Pump the brake pedal a few times to seat the brake pads before driving.
